Gasoline standards for three countries and four regions
Thread Content
I would like to ask everyone: have the National III and National IV standards for diesel and gasoline been released? If anyone has a copy, I would be extremely grateful! ! !
Key specifications for clean gasoline at home and abroad: Parameter – Sulfur, ug/g; Olefins, v%; Aromatics, v%; Benzene, v%. Implementation year: Euro III (EN228-99): ≯150, ≯21, ≯42, ≯1.0; 2000. Euro IV (2003/17EC): ≯50, ≯18, ≯35, ≯1.0; 2005. Euro V (ULSG): ≯10; 2009. US TIER II-1: ≯120; 2004. US TIER II-2: ≯90; 2005. US TIER II-3: ≯30, ≯14, ≯30, ≯1.0; 2006. GB17930-1999: ≯800, ≯35, ≯40, ≯2.5; 2003. National II gasoline: ≯500, ≯38, ≯44, ≯2.5; 2005. National III gasoline: ≯150, ≯30, ≯35, ≯2.0; 2009. National IV gasoline (Beijing): ≯50, ≯25, ≯35, ≯1.0; 2008. National IV gasoline (nationwide): ≯50, ≯25, ≯35, ≯1.0; 2010–2011
The standards for the 2nd floor don’t seem correct; for National III gasoline, the benzene content should be no more than 1%, and the aromatic hydrocarbons should be no more than 40%, right?
National Standard III gasoline was implemented nationwide on December 31, 2009. Some large cities, such as Beijing, have begun to implement local standards equivalent to Euro IV. Standard National IV has not been officially introduced yet; it is estimated that the sulfur content in gasoline will be kept at no more than 50 ppm.
The National III diesel standard has been officially released; it is a standard for diesel used in vehicles, and it does not belong to the same series as the light diesel standard that is currently in use. In other words, in the future, National III diesel for vehicles and light diesel may need to be used alongside each other. The National III standard for vehicle diesel will be officially implemented in the second half of 2011. Key specifications: sulfur content not exceeding 350 ppm; cetane number: 0# at least 49, -20# at least 46, -35# at least 45. And specifications were set for density and polycyclic aromatic hydrocarbon content.
